My PC is very loud in a new case even though everything seems to be ok.

Hello!

I just changed my pc into a new case Zalman z3 Plus and also installed a new cooler Scythe Tatsumi cpu cooler and the pc is very loud. Any suggestions on what can I do to make it more silent?
The temp are ok on heavy browsing session: cpu 33C and gpu also 33C

My specs:
cpu: Intel I5-4460 @3.20 GHz
mobo: AsRock B85M-DGS
gpu: NVIDIA GeForce GTX660
ram: 16 gb ddr3
psu: Sirtec - BRONZE 500W

Any help would be greatly appreciated.

Can you pinpoint whee the noise may be coming from? IS it loud just sitting there at idle?

 

[plastichellhamer]

Yes, it's loud just idling, doing nothing, the noise is constant.
I suspect the noise might be comingfrom my new CPU Cooler, because since I installed it it today, the computer sounds louder than before and it's the only thing that's changed.

You CPU cooler is plugged into the CPU_FAN header and not a SYS_FAN header?

The CPU cooler is plugged into PWR_FAN1

The CPU cooler is plugged into PWR_FAN1

That's why. Your fan is running at fan speeds all the time, and it's not be regulated by the motherboard. Plug it to the CPU_FAN header.

Slip Stream 92 mm fan rotates in a range between 300 and 2.500 RPM thanks to PWM control and moves between 11,4 and 94,3 cubic meter per hour (6,70 to 55,55 CFM) at merely audible 7,2 to 31,07 dBA.

PWR_FAN1 is the wrong fan header. CPU Fan Connector (CPU_FAN1) is the correct header.

Right now CPU_FAN1 is occpied by one of the case's fans, the backsie one. My question is, should I switch them? or should the fan go somewhere else?

Yes. Only the CPU cooler should go in the CPU_FAN. Right now your CPU cooler is running like a case fans, which is probably 100% all the time. Your case fans, is probably running a bit low. Switch them, and you should notice a change.

Thank you, Herc08! The problem was that the CPU cooler was not plugged into the CPU_FAN slot. Now that I switched it, the computer is almost completly silent, I couldn't believe it was fixed.
